Causes and Preventive measures of Sweet Potato malformation

Sweet potato, also known as sweet potato and sweet potato, is an annual herb, rich in protein, starch, vitamins and minerals, as well as anti-cancer, diabetes prevention and weight loss. However, the phenomenon of abnormal growth will occur when sweet potato is planted, which will cause certain losses to farmers, so what is the reason for the deformity of sweet potato? Let's take a look at the pro-farm network.

Cause of malformation

1. Continuous cropping and lack of nutrition: long-term continuous cropping of sweet potato will lead to serious harm of diseases and insect pests, resulting in deformities. In addition, when planting, many farmers are used to applying nitrogen, phosphorus and potassium fertilizers, especially a large amount of nitrogen fertilizer, resulting in exuberant vine growth and affecting the absorption of other trace feed, while calcium, boron and other elements are essential substances for plant growth. Lack of these trace elements, resulting in sweet potato skin thinning, loss of elasticity, resulting in cracking resulting in deformity.

2. Drug residues: in the cultivation of sweet potatoes, the previous drugs were overused, resulting in certain drug residues in the cultivation of sweet potatoes, which will affect the growth of sweet potatoes and cause growth deformities over time.

3. The application of organic fertilizer is not completely mature: mentioned above, there is a lack of trace elements, while organic fertilizer or farm fertilizer is rich in these elements, which can meet the growth needs of sweet potato, but some farmers do not fully mature when applying these organic fertilizers. as a result, the organic fertilizer will emit a lot of heat when it is decomposed, resulting in root burning, resulting in malformed growth of sweet potato tubers.

4. Diseases and insect pests: sweet potatoes will suffer a lot of diseases and insect pests when they are planted, which will cause damage to them, such as stem nematodes, black spot, golden needle insects, grubs and other diseases and insect pests will cause deformities.

There are many reasons for the deformity of sweet potatoes, such as varieties, heavy soil or a large number of stones, stones and other hard objects, as well as improper management of water and fertilizer, or early grabbing of nutrients in the field.

Precautionary measures

In view of the above causes of deformities, prescribe the right medicine to prevent deformities.

1. Continuous cropping will cause serious damage to diseases and insect pests and cause deformities, so we should rotate crops reasonably and rotate with other crops to avoid losses caused by continuous cropping. In addition, fertilization should be matched reasonably and should not be applied singly or partially, so as to avoid excessive growth of plants and affect the absorption of trace elements.

2. Pay attention to the dosage and concentration of the drug, check the drug residue when planting, and avoid the land where the drug residue exceeds the standard as far as possible.

3. When applying organic fertilizer and farm manure, it must be completely mature and then applied.

4. We must pay attention to the prevention and control of diseases and insect pests, deal with them in time when they are found, and take corresponding measures to prevent and control them.

5. Select varieties with high yield, high yield and strong disease resistance when planting, strengthen water and fertilizer management after planting, and water and fertilize according to plant growth and climate change in a planned way, so as to avoid cracking and deformity of sweet potato when it expands quickly.

The above are the causes and preventive measures of sweet potato deformities brought by the pro-agricultural network. I hope it can help you. If you want to know more about sweet potato planting, please pay attention to the pro-agricultural network.
